problem with d link DFE-538TX Ethernet card

I have a problem with d link DFE-538TX Ethernet card I'm trying to fix and update a computer for my grand niece who struck in a wheel chair after a 2 leg operation&#8212;so she can have some fun playing game etc-- but not to be

I'm upgrade their old machine from me to xp and that when good but geting the card to work with XP is a nitemare-- noting i do work&#8212;it give me noting but a problem-- first off xp does not even see it&#8212;all I get is in device manager &#8211;other devices-Ethernet controller with a bit yellow ? beside it

yes i found a driver for xp-- but it does not work-- see can not see the card-- tryed run cmd ipconfig and noting show up-- xp try to find hardware but will not accept driver to make card work-- i even reinstall xp to clean format with cable plug in from rounter-- noting xp did not even find it

if XP does not find it and some say it suppose to but does not-- driver did not work /even try it a few time- and changing PCI slot does not work either-- not much left-- it has to be the card-- even if the green led light on both on-- but card work in window 7-- but now it seem i can not get xp to axcept drive for card

just for the hell of it i took card out and put it in my window 7 machine- and it found it-- i wrote this reply using that card

in device manager i found network adapter-dlink dfe-538tx pci Ethernet adapter-- but i also found other devices/ unknown device with a yellow ? beside it---

now im back to square one-- card work but it does not accept driver in xp-- no idea as to why
